my aunt is visiting my parents and im here visiting too, she was telling me even when she has the AC on the passenger side will blow cold air, but her side will still blow heat. i know nothing about volvos so i checked the fuses in the engine bay and didnt see any probs. she does not have her owner manual so i cant check the ones under the dash.

she also said the driver side seat heater no longer works. seen something on the internet about a relay under it but i couldnt find one.

anyone have any ideas on what it could be, or where i could get the info from the owners manual on the internet?
